It is completely removed for connection processes, because assuming Cowboy is written properly this should bring us nothing anymore in 2.0. It is reworked for request processes, there we want to always propagate the stacktrace (including for exits) because we will print a report to help with debugging and proc_lib doesn't propagate it for exits. At the same time the initial callback for connection and request processes has been changed to connection_process and request_process, which should help with identifying processes when inspecting.
